How to configure Suse Linux Server 9 for online update

Hello Members,
I am new in Suse-Linux Server 9. I installed the suse on my desktop system now i am trying to online update through my office proxy server with user password.
What i did ?
I provided the correct proxy address in my proxy information at system level and also provided the user password there in /etc/sysconfig/proxy but still when i am trying to online update or running konqueror web browser it returns the message credential fail. Authentication Required. How can i supply credentials to my newly installed suse box.
